Mariner 8 677 UL 700701 tried to add a pic it wouldn't let me I had made another post with the serial number included, I think you replied to that one as well.
No kinks in fuel line, vent open, bulb primed, fired up and runs for about 15-20 seconds then dies and the bulb is completely soft. If primed again it fires up easily again. Took the diaphragm apart and put it back together haven't tried it yet. Will tomorrow
I am looking for info on this motor.
Cleaned carb after sitting, it fires up first pull when primed but it's not pulling fuel after the bowl runs out.
Suggestions
